[jira] [Comment Edited] (CASSANDRA-7950) Output of nodetool compactionstats and compactionhistory does not work well with long keyspace and column family names.

------------------------------------------------------------

Might be worth looking into how the column command does it.  e.g.:

  cat /proc/meminfo
  cat /proc/meminfo | column -t

At the very least if these nodetool commands had proper delimitation (e.g. at least a single space between fields) their output could be easily parsed by utilities and the column command could be used manually to correct the output.

> When running these commands:
> nodetool compactionstats
> nodetool compactionhistory
> The output can be difficult to grok due to long keyspace names, column family names, and long values.  I have attached an example.
> It's difficult for both humans and grep/sed/awk/perl to read.
